Description

(5) MULTI-POINT DETERMINATION DEVICE

one

This invention relates to a product structure and can be used. long recording the results of single-type analyzes with several analyzed lines.

According to the main auth. ff is known a multipoint registration device containing a valve, an analyzer, a registration unit with a motor and a multipoint switch, a logic unit, a programmer, a multi-input element AND, a relay blocking the input of the registration unit and an electronic time relay 1 The disadvantage of the known device is the possibility of recording the analysis results Only one component of the analyte.

The purpose of the invention is to reduce the time of registration while simultaneously analyzing two. And more components of the analyte.

The goal is achieved by adding additional registration units with a multipoint switch and a motor, analyzers connected between the distributor and the inputs of the registration blocks,; the blocking relay inputs of the registration block, as well as two-input elements And and equivalence elements, with the first input two-input element And connected to the common output of a multipoint switch, the second input - with the output of the multiple input of the element And, the output - with the relay "and the first input of the equivalence element, the second input which is connected to the output of the time relay, the output of the element of equivalence is included in the power supply of the engine of the registration unit, and the corresponding outputs of all multipoint switches are connected

20 in parallel.

The drawing shows a block diagram of a device for registering two components of an analyte. The device contains a distributor 1, to which the analyzed lines 2 are connected, analyzer 3 registration block k with engine 5 and multipoint switch 6, relay 7) logic block 8, programmer Etmnogovodoy element I 10, electronic time relay 11, two-input element I 12, element 13 equivalence, additional analyzer 1, additional registration block 15 with engine 16 and multi-point switch 17 and additional relay 1.8. The operation of the device is as follows. When the signals from the multipoint switch 6 and the programmer 9 coincide, a signal appears at the inputs of the logic unit -3 at the corresponding output of the latter. At that, the corresponding analyzed line 2 through the distributor 1 is connected to analyzers 3 and 1A and the state of the multi-input element AND 10 changes. The signal from the output of the multi-input element And 10 is fed to the second input of the two-input element And 12 and starts the electronic time relay 11, which generates a signal at the second input of the element 13 of equivalence and turns off the power supply voltage of the engine 5. At the same time, the signal from the output of the multi-input element I 10 switches on the relay 7, which connects the output of analyzer 3 to the recording unit 4. At the same time, the registration unit 15 sequentially goes around the points to the control unit and when the point number on the registration unit 15 and the point number from which the analysis is currently being analyzed coincides, the signal to the first input of the two-input element I 12 is output from the multipoint switch 17. Element 12 includes a relay 18, which connects the output of the analyzer 14 to the input of the registration unit 15 and sends a signal to the first input of the equivalence element 13. The equivalence element shuts down the power supply voltage of the engine 16. After a dwell time (analysis cycle time), the electronic time relay 11 supplies the supply voltage to the engine 5 of the recording unit k and removes the signal from the second input of the equivalence element 13, which supplies the supply voltage to the engine 16 block 15 registration. The number of the analyzed line and the value of the output signal from the corresponding analyzers 3 and} k are fixed on the diagrams of blocks and registration 15, and the multipoint switches 6 and 17 are moved to a new position. If the next program point is on, the system operation is repeated, but if the point is turned off, then relays 7 and 18 block the corresponding registration blocks i and 15, and motors 5 and 16 continue to rotate and the given point is fixed at zero of the registration blocks. The two-input element 12 and the equivalence element 13 ensure synchronous operation of the registration block 15 with respect to the registration block k, which allows simultaneous recording of signals from analyzers 3 and 14. If necessary, record n components of the analyte in the system are entered (p-1 a) additional devices. Claims of the invention Multipoint recording device according to author.
